Battle of Awa

Battle of Awa. The Battle of Awa was a naval engagement fought on 28 January 1868, during the opening stages of the Boshin War. It marked the first naval conflict between the forces of the ruling Tokugawa shogunate and the imperial-aligned Satsuma Domain. The battle, occurring in the waters off Awa Province near Osaka Bay, was a relatively minor but symbolically significant clash that demonstrated the importance of modern naval power in the conflict.

Background

The battle took place in the immediate aftermath of the Battle of Toba–Fushimi, where the combined forces of Satsuma Domain and Chōshū Domain had secured a decisive victory over the Tokugawa shogunate. Following this defeat, the shogunate's Shōgun Tokugawa Yoshinobu retreated from Kyoto to Edo. Meanwhile, a shogunal naval force under the command of Enomoto Takeaki, a prominent naval officer trained in the Netherlands, was stationed in the Seto Inland Sea. This fleet, which included the powerful corvette *Kaiten* and several other vessels like the *Banryū*, was tasked with securing maritime routes. Opposing them was a smaller squadron from Satsuma Domain, which had been actively procuring modern warships such as the *Kasuga* and was commanded by Akatsuka Genroku. The political landscape was defined by the declaration of the Meiji Restoration and the Satchō Alliance against the Tokugawa shogunate.

Battle

On the morning of 28 January, the Satsuma Domain squadron, consisting of the *Kasuga*, *Hōō*, and *Heiun*, was sighted near Hyōgo by the larger Tokugawa shogunate fleet. The shogunate force, led by Enomoto Takeaki aboard the *Fujiyama*, included eight vessels such as the *Kaiten*, *Banryū*, and *Chiyodagata*. Akatsuka Genroku ordered his ships to form a line and engage. The shogunate's ships, benefiting from superior numbers and firepower, concentrated their cannon fire on the Satsuma flagship *Kasuga*. During the exchange, the *Kasuga* sustained significant damage to its hull and rigging, while the *Heiun* was also engaged. The Satsuma Domain squadron, recognizing it was outgunned, utilized its steam propulsion to disengage from the battle and retreat towards Kagoshima Bay. The Tokugawa shogunate fleet did not pursue aggressively, partly due to concerns over ammunition and the political uncertainty following the Battle of Toba–Fushimi.

Aftermath

The battle was tactically inconclusive but represented a minor victory for the Tokugawa shogunate, as it had forced the retreat of the Satsuma Domain squadron without losing any of its own ships. However, this naval action had little strategic impact on the overall course of the Boshin War. The damaged *Kasuga* was successfully repaired and later participated in key engagements like the Naval Battle of Miyako Bay. For Enomoto Takeaki, the battle proved to be a prelude to his more significant later command of the shogunate's remnant forces, which would eventually establish the Republic of Ezo in Hokkaido. The engagement underscored the naval dimension of the conflict and highlighted the technological transition within the Japanese navy from traditional vessels to modern, steam-powered warships. The event is commemorated at sites like the Shōkonsha shrine in Tokyo.

Order of battle

The Tokugawa shogunate fleet was under the overall command of Enomoto Takeaki. Its core combatants included the steam corvettes *Fujiyama* (flagship) and *Kaiten*, the auxiliary steamer *Banryū*, the gunboat *Chiyodagata*, and several other armed transports and auxiliary vessels such as the *Shinsoku*. The Satsuma Domain squadron was commanded by Akatsuka Genroku. His force consisted of the steam corvette *Kasuga* (flagship), the auxiliary steamer *Hōō*, and the transport *Heiun*. Both sides utilized a mix of Armstrong and Krupp artillery, with the shogunate's ships generally possessing a quantitative advantage in both numbers and broadside weight.
